The distance from the person to the base of the cliff is 269.78 meters.

The height of the building from the base of the cliff is 829.37 meters

The situation forms right angle triangle.

The building is constructed on top the cliff that is 300 meters high.

Right angle triangle has one of its sides as 90 degrees. Therefore, the sides can be found using trigonometric ratios.

The height of the building from the cliff is 300m. let's find the hypotenuse side of the angle of elevation formed to the cliff.

Using sin rule,

300 / sin (72 - 63) = y / sin (180 - 162)

300 / sin 9 = y / sin 18

300 sin 18 = y sin 9

y = 300 sin 18 / sin 9

y = 92.7050983125 / 0.156

y = 594.230769231

Therefore, how far the person to the base of the cliff can be calculated as follows;

cos 63 = adjacent / hypotenuse

cos 63 = x / 594.2307

x = 594.2307 cos 63

x = 269.775092454

x = 269.78 meters

Therefore, the distance from the person to the base of the cliff is 269.78 meters.

height of the cliff  / 269.78 = tan 63

height of cliff = 269.78 tan 63

height of cliff = 529.37493165

height of cliff = 529.37

The height of the building = 300 + 529.37 = 829.37493165 = 829.37 meters

The full form of HA is Hypotenuse-angle and it states that if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.

Answer:

HA

Step-by-step explanation:

Usually HA congruence is used in right angle triangles .as One common 90° right angle is present if Hypotenuse and adjacent angle remains similar the triangles are similar.

Applying the exterior angles theorem, the measure of the exterior angle is: m∠2 = 139°.

The exterior angles theorem states that the measure of the two remote angles in a triangle is equal to the measure of the exterior angle of a triangle.

Thus:

75° and 64° are remote interior angles.

Therefore:

m∠2 = 75° + 64°

m∠2 = 139°

Answer:

x=134

Step-by-step explanation:

As angles in a triangle add up to 180 degrees

also angles on a straight line add up to 180

so 180-(64+70)=46

and 180-46=134

Step-by-step explanation:

Let me start off by saying that 1 unit side is absolutely useless.

You can translate the 6 unit side downwards, so now we have a right isosceles triangle of 2 equal sides which are 6

The hypotenuse is given here by x.

Applying the Pythagorean theorem i can then say;

[tex]x {}^{2} = 6 {}^{2} + 6 {}^{2} [/tex]

[tex]x {}^{2} = 36 + 36[/tex]

[tex]x {}^{2} = 72[/tex]

[tex]x = \sqrt{72} = 6 \sqrt{2} = 8.485[/tex]

x=8.5

rounded to the nearest 10 :)

i think it should be -1.6

if you add 7 to 9 it'll be 16.

if you divide -10 by 16 it'll give you -16/10.

simplify it and you should get -8/5 or -1.6.

Answer:

[tex]M = (3,5.5)[/tex]

Step-by-step explanation:

Given

[tex]A = (-1,8)[/tex]

[tex]B = (7,3)[/tex]

Required

Determine the midpoint

This is calculated as thus

[tex]M = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex](x_1,y_1) = (-1,8)[/tex]

[tex](x_2,y_2) = (7,3)[/tex]

So, we have:

[tex]M = (\frac{-1+7}{2},\frac{8+3}{2})[/tex]

[tex]M = (\frac{6}{2},\frac{11}{2})[/tex]

[tex]M = (3,5.5)[/tex]

Hence;

The midpoint is (3,5.5)

Trust me I got it right on Khan

Step-by-step explanation:

[tex]\displaystyle \boxed {y = sin\:(x + \frac{\pi}{2})} \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-\frac{\pi}{2}} \hookrightarrow \frac{-\frac{\pi}{2}}{1} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{2\pi} \hookrightarrow \frac{2}{1}\pi \\ Amplitude \hookrightarrow 1[/tex]

OR

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{2\pi} \hookrightarrow \frac{2}{1}\pi \\ Amplitude \hookrightarrow 1[/tex]

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the cosine graph, if you plan on writing your equation as a function of sine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = sin\:x,[/tex]in which you need to replase "cosine" with "sine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the cosine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the sine graph [photograph on the right] is shifted [tex]\displaystyle \frac{\pi}{2}\:unit[/tex]to the right, which means that in order to match the cosine graph [photograph on the left], we need to shift the graph BACKWARD [tex]\displaystyle \frac{\pi}{2}\:unit,[/tex]which means the C-term will be negative, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{-\frac{\pi}{2}} = \frac{-\frac{\pi}{2}}{1}.[/tex]So, the sine graph of the cosine graph, accourding to the horisontal shift, is [tex]\displaystyle y = sin\:(x + \frac{\pi}{2}).[/tex]Now, with all that being said, in this case, sinse you ONLY have a wourd problem to wourk with, you MUST use the above formula for calculating the period. Onse you do that, the rest should be easy. Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 0,[/tex]in which each crest is extended one unit beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

Option C .

Step-by-step explanation:

Here it is given that there are two species of birds which fly at different rates.

We can use the formula here ,

[tex]\longrightarrow \red{ Speed =\dfrac{Distance} {Time} }[/tex]

For Species A :-

Substitute the respective values in stated formula ,

[tex]\longrightarrow v_A = \dfrac{18.9\ miles}{42min}\\[/tex]

Simplify ,

[tex]\longrightarrow v_A = 0.45\ miles / min [/tex]

For species B :-

Substitute the respective values in stated formula,

[tex]\longrightarrow v_B =\dfrac{20.3\ miles}{58min}\\ [/tex]

[tex]\longrightarrow v_B = 0.35\ miles / min [/tex]

Therefore from above calculations we can say that ,

[tex]\underline{\underline{ v_A > v_B }}[/tex]

Species B is slower and it can fly 0.35miles/minute .
